To all whom it may concern:

Be it known that I, JOSEPH O. EARNSHAW, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Double- Faced Woven Fabrics, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, which forms a part of this specification, and in which there is illustrated diagrammatically in section, taken in the dIrection of the warps'i. e., transversely 'of the weftsa fabric embodying features of the invention.

The object of my invention is to produce a double ply fabric, suitable for curtains, draperies, or the like. A fabric embodying the invention has as one of its plys a warp predominating cloth of known weave formed by the interweaving of warp-threads, and buried weft-threads, the warp-threads being sufficiently numerous to produce upon a ground, commonly known as a rib or a rep, (in which alternate warp-threads pass over and under the weft threads) a figure, formed by warp-threads floating over weft-threads. The other ply of the fabric embodying the invention is a Weft predominating cloth of known weave formed by heavy weft-threads and fine warp-threads the fine warp-threads being only sufliciently numerous to, when passed alternately over and under the weftthread, form a fabric. The Weft-threads may also be used to form a figure, by floating them or some of them over two or more warp-threads, as may be required by the des1 11. di vision of the warp-threads into alternate dark and light warp-threads, which in combination with the weft-threads, serve to produce figure effects, caused by the difierence in shade, which the weft-threads assume, when bound,as the design may require,- by either dark or light warp-threads; the warp of either color, which is not required for the use on the face, meanwhile floating between the two plys.

In practice I can use an equal number of weft-threads in both plies, or I may vary the proportionate number of the weft-threads in either ply as required by various qualities of cloths, which I maydesire to produce.

This ply may be further varied by the I am enabled by the use of the weavers art, to produce in the finished fabric the first ply on the face, the second ply on-the back or their position may be reversed, the second ply on the face and the first ply on the back, as may be required by the design. The complete fabric is joined only at those points where the two clothsintersect in passing from face to back or back to face and at all other points is two separate an independent fabrics forming as it were a series of bags or pockets. In these two cloths, by reason of their independent nature, the number of weft threads per inch may be the same or may be varied in either cloth without aflecting the other cloth. Furthermore the ba like or pocketed structure imparts to the abric qualities which especially ada t it for draping purposes.

he construction of my improved fabric may be readily understood by reference to the accompanying drawing.

The fabric in one ply is composed of the warp-threads A, and B, and the weft-threads F, and in sections 1, 3, and 4, it appears on the top or upper ply, while in section 2, it appears on the lower ly. This 1y is a warp predominating cloth 1n which t e figure f is raised and, is formed by bringing the entire warp required for the figure to the face and ermitting the weft to float on the back between the two plies and in which the ground g, is formed or produced by interweaving alternate warp-threads with the weft-threads after the fashion of plain weavin g. The other ply is composed of fine war threads C and D, and heavy weft-thread and in sections 1, 3, and 4 it appears on the lower ply, while in section 2, 1t appears on the up er ply. In sections 1, and 2, I show the we t-threads in both upper and lower plies to be of equal number; in section 3, the lower ply has only one half as many weft-threads as the upper ply; while in section 4, the upper ply has only one-half as many weft-threads asthe lower ply. The proportionate number of the weft-threads, in either ply in section 3, and 4., may vary, as required by the various ualities of cloths. This ply is a weft-preominating cloth which may be plain woven, as at h, or figured by floating wefts as at m, over the warp which goes to the back betweenthe pliesf Having now fully described my invention, warp to the face and permitting the weft to what I claim and desire to protect by Letters float between the two cloths and in which Patent is: the ground is formed by interweaving alter- "A double ply drapery fabric formed by the nate warp threads with weft threads, sub- 5 combination of two cloths independent of stantially as described.
